Thus, with frequent unavoidable vathe full height of the post and being finished riations in the height of strike or hinge plates to match the :same.

The illustration also indicates a cavity 23a cut in the surface of the wood strip or insert for the sinking of the hinge or strike plate to the desired depth. Thus, the frame can be constructed at the factory to include the wood facing and without the need of any door hardware specifications, the hardware being applied in the ordinary way at the site of installation.

\Vhile the wood facing in the door frame is not essentially novel, it will be noted that the facing in my case is particularly constructed and retained. The strip 23, while of generally oblong cross section to fit the channel in which it seats, is also cut in the outer side edge with a deep groove 24 in which is lodged the doubled joint of the channel and side 23, as formed by parts 21 and 22. The wood strip 23 not only seats in the channel, but is locked in two places, first by the section 17 and by the joint just mentioned, which is in the form of a tongue seating in the groove 24. With the parts accurately made and fitted at the factory, it will be appreciated that the strip 23 is virtually an integral part of the post or door buck, and finds in the latter a firm and durable support. Also, being of full height, the strip or insert cannot sag or shift from the weight of the door.

The above installation is suitable in most instances where metallic door frames are desirable and not specified as fully fireproof. However, in the latter case, not only are the door frames specified as fireproof but even the doors are metal, so that the wood insert 23 would fail of approval. To suit fully fireproof installations, I have designed a modification of the insert described, comprising of a full-height facing of metal. As shown in Figure 4, this facing follows the general outer contour of the wood facing, but has no inner side. Thus, the modified facing comprises a frontal section 25, an inward bend 26 at one side and applied within the frame section 17, a short inward bend 27 to meet the side 13, a lateral channel 28 from the bend 27 to engage the locking tongue 20, 21, 22, and a final short inward bend 29 extending to the internal facing 12. In this installation, the insert facing would necessarily have to be made at the factory to specifications including those for the strike and hinge plates. However, in case of error developing in the production of the inserts, whereby difficulty or waste results only the insert is risked and not the entire frame post.

Thus, the latter may be kept in stock and inserts made up with dispatch to specifications.

It will be seen that in the main and modified embodiments I have fitted the insert firmly and durably into the frame post by a particular locking arrangement. Yet, no

special parts or fastening elements are used, and no difficulty or hardship is presented to the factory for the formation of the assembly. In fact, the ultimate economy by producing the frame with the improved features will more than offset the cost of any equipment necessitated by the change from the prevalent design.

I claim:

1. A jamb facing comprising a column having sides and a front, an offset portion of the front constituting a door stop, a recessed section extending away from said door stop and defining a pocket having a key, and a facing member lodged in the pocket and locked by the key.

2. A jamb facing comprising a column having its front offset to form a door step, a section of the front extending away from the door stop to define a pocket, a facing member seated in the pocket, and cooperating means in the pocket and facing member for locking the latter in place.

3. A jamb column having its front offset to form a door stop, a section of the front offset-in a direction reverse from the stop, a facing member seated in the section and means for locking the member in position.

4. A jamb facing comprising a section frontally recessed, said recess defining a seat substantially rectangular in cross section, a flange extending within the seat, a facing member having a slot medially therethru, said member lodged in the seat thru the locking engagement of the flange and slot.

In testimony whereof I afiix my signature.
